Who can help my mother with old policy Rio Grande National Life Insurance?

We have old policies that we need to inquire about they are from Rio Grande National Life Insurance from 1961. Or who I can call the last information I saw from Tx. Dept. of Insurance that they were merged with Kentucky Central Life Insurance Company, but they cancelled. Thanks
